I wish The Sims 3 was 64 bit instead of 32 bit

I dream of a 64-bit version of this game but it won't happen.

When I'm playing a big save with all packs, store, and I think 2gb worth of CC+mods on maxed graphic settings... The game crashes around the 4-5 hour mark (sometimes 6). Crash log analyzer tells me it's the game hitting the ram limit which I guessed. The way to prevent this in my case would be to save, close out, and launch the game again. Apparently I can't be bothered to do that.
